Hi Sharmila, Jai shri krishna
Traditionally Singhi jo Saag is eaten with Phulko by the Bhatias. The consistency should curry consistency. This is one of the few dishes where the gravy is on the thinner side and not like a puree. The more potatoes you add in the dish, the thicker it gets.
It is also a matter of personal preference as to how thick you want the Saag to be…enjoy the dish….
